The Spanish Securities Commission (CNMV) issued Circular 3/2025 updating the statistical information that collective investment institutions, venture capital entities and EU closed-end collective investment undertakings must report, aligning the reporting templates with the European Central Bank’s Regulation (EU) 2024/1988. The circular revises existing statistical statements and introduces new ones, including a new return on participants (OIF7) to collect information needed to comply with ECB Regulation (EU) 1011/2012. The revised framework adds country breakdowns and new fields on entity identification and participants, and sets out which OIF (other financial intermediaries) statements firms must submit and their reporting frequency. It also establishes criteria for size-based exemptions under which exempt entities submit less information less often, and notes that non-compliance is sanctionable. The scope includes collective investment institutions (including money market funds in part), venture capital companies and funds (including SME variants), closed-end collective investment companies and funds, and European venture capital, social entrepreneurship and long-term investment funds. Circular 3/2025 enters into force on 17 July 2025 and applies from 1 December 2025, repealing Circular 5/2014 and Circular 5/2008.
